Anyone heard of a Z-Amp, its a brand I saw at a local high-end audio shop, the only thing they could tell me was it was a gainclone. Come with two silver block aluminium one the amp and the other the power supply. No labels on the company or model just Z-Amp silkscreened onto the front. I did a google and couldn't find anything on it.

If you are going to sell something like this through dealers, and live off the profits left the price is ballpark.
Dealer cost would be 1440.00. Amp parts cost say 250.00. That is about normal markup from parts cost to delivered product.
Some people do not build anything. So the 250.00 parts is not even an option. But still 2400.00 for what is shown is way out of line.
